Alert, Confirm, and Prompt boxes in Javascript

The three "commands" involved in creating alert, confirm, and prompt boxes are:
  • window.alert()
  • window.confirm()
  • window.prompt()
window.alert() : This command pops up a message box displaying whatever you put in it. 
 
<body>
<script type="text/javascript">
window.alert("Iam an alert box!!!")
</script>
</body>
window.confirm(): Confirm is used to confirm a user about certain action, and decide between two choices depending on what the user chooses. 
 
<body>
<script type="text/javascript">
var x=window.confirm("Are you sure?")
if (x)
window.alert("Yes!")
else
window.alert("No")
</script>
</body>
window.prompt(): Prompt is used to allow a user to enter something, and do something with that info:
 
<body>
<script type="text/javascript">
var y=window.prompt("Enter your name here...")
window.alert(y)
</script>
</body>

Always write script in file with extension ".js". functions.js: function imageswitch(){ var image = document.getElementById('switchimage'); if(image.src.match("one")) { image.src = "flower_two.jpg"; } else { image.src = "flower_one.jpg"; } } Note: Make sure that the both html and js file locations are the same or else defime them specifically
